"A little over a year ago, we told you about NASA’s Green Flight Challenge that is offering US$1.6 million in production funds to the winning design for a for low-cost, quiet, short take-off personal aircraft, that require little if any fossil fuel.

"Walk barefoot on an asphalt road and you'll soon realize how good the substance is at storing solar heat – the heat-storing qualities of roadways has even been put forward as an explanation as to why cities tend to be warmer than surrounding rural areas. Not content to see all that heat going to waste, researchers from the University of Rhode Island (URI) want to put it to use in a system that harvests solar heat from the road to melt ice, heat buildings, or to create electricity." | more

"Yes, there are real-life superheroes. And no, we’re not just referring to firefighters, paramedics, and other heroic people who we’re used to seeing coming to the rescue of others. We’re talking about costume-wearing, identity-concealing, cool-name-having people who fight crime, pollution, or other evils in their own communities, on their own time, and at their own risk. Many of them actually patrol the city streets, ready to intervene if they see trouble brewing – and being ready includes having the right tools.

"Research has already shown that at the nanoscale, chemistry is different and the same is apparently true for light, which Engineers at Stanford University say behaves differently at scales of around a nanometer. By creating solar cells thinner than the wavelengths of light the engineers say it is possible to trap the photons inside the solar cell for longer, increasing the chance they can get absorbed, thereby increasing the efficiency of the solar cell.

Shooting in 3D has traditionally required a complex, bulky and fragile rig using two cameras and additional hardware to calibrate and adjust them. Panasonic's straight-forwardly-named Twin-lens Full HD 3D camcorder looks to radically change the 3D game, with integrated lenses and dual memory card slots allowing you to capture 3D footage immediately, with just one device.

The camcorder records onto inexpensive SDHC/SD memory cards, thankfully abandoning the P2 system used for its concept 3D camera, and the outrageously expensive P2 memory cards along with it.
